2.5MHz, 1A Synchronous Step Down Regulator In SOT23-5

The SC4626 is a high efciency, synchronous Step-down Regulator providing up to A output current in a SOT23- 5 package. The device requires only three external flter components for a complete Step-down Regulator solution. The input voltage range is 2.9 to 5.5V with factory programmed outputs from .0 to 3.3V. The converter operates at fxed 2.5MHz switching frequency allowing small L/C fltering components. The voltage mode architecture is compatible with chip inductors and capacitors for minimum PCB footprint and lowest overall system cost. Up to 93% efciency is achieved with low RDS(ON) internal switches. PWM constant frequency operation ensures low output ripple across the load range. 00% duty-cycle provides 300mV dropout voltage at A which extends the minimum input voltage for 2.5V and 3.3V outputs. Excellent transient response is achieved with no external compensation components. The SC4626 provides input under-voltage, output over- voltage, output short circuit and over-temperature protection to safeguard the device and system under fault conditions. The Regulator provides integrated soft-start to minimize inrush currents. Standby quiescient current is less than A. By Semtech Corporation
